Test (Regression)

The Test section specifies the data used for testing and the tests performed. By default, all models that are built using test data are tested. The test data is created randomly splitting the build data.

The following settings are available in the Test section:

• Perform Test: By default, all models that are built using test data are tested. The test data is created randomly splitting the build data.
  The default test results are:

  • Performance Metrics

  • Residuals

    You can deselect both.

• Test Data: Test Data is created is one of the following ways:

  • Use all of the Mining Build Data for Testing

  • Use Split Build Data for Testing
    Split for Test (%)
    Create Split as: View (default). The split creates a view that is not parallel.

  • Use a Test Data Source for Testing: Select this option to provide a separate test Data Source and connect the test data source to the build node after you connect the build data. Alternately, you can test a model by using a Test node.
